Operational Information
The Mr. Heater Electric forced air heaters are designed to be
used by professionals.
Heat is created by electric current passing through coiled metal
elements bringing them up to very high temperatures. The fan then
passes room air over the hot elements exchanging cold air for warm.
The air moving over the coils keeps them from reaching
temperatures that are not safe for the normal operation of
the heater. However it is important to keep all combustible
materials and any objects that may be sucked into the fan
blades at a safe distance (please refer to the specification table
for appropriate clearances). Make sure that the fan blades
remain unobstructed at all times. Keep unit clean and dust free.
Do not block unit intake or exhaust at any time.
These units are designed to be used only with the cord and
plug supplied with the unit. Do not use any plug other than the
one supplied by the manufacturer. For information on which
receptacle is appropriate, Refer to Figure 1 and find the diagram
that corresponds to your heater.
If damage has occurred please refer to the parts listing in this
manual and contact the manufacturer for a replacement.
WARNING: Outlet must be properly grounded, failure to do
so may result in electric shock or property damage.
WARNING: Always plug heaters directly into a wall outlet/
receptacle. Never use with an extension cord or re-locatable
power tap (outlet/power strip).
